She alleged that Mabe had made advances on her, slashed her salary, demoted and emotionally abused her after she rebuffed his sexual advances on at least two occasions.

In the letter, the 26-year-old alleged that Mabe booked a room for her close to his at the Saint George Hotel in Irene, southeast of Pretoria, under the pretence that the two would be doing ANC work.

She said on the first night, Mabe came to work in her room and at some point asked her to sit closer to him. She claimed that on the second night, Mabe insisted on working on his assignment in her room, saying he would fall asleep were he to do so alone.

She detailed how during one of the occasions Mabe climbed into her bed while she was asleep and got under the blankets, putting his legs on top of hers.

In his responding affidavit presented to the panel, Mabe said he reduced the salary of his accuser because she made "fraudulent misrepresentations" about her qualifications.

In a statement this week, the party indicated that the matter was now closed.
